5 PSI | 130 WHP | 175 Crank HP | 91 Octane
Turn your Polaris Xpedition into the machine it should’ve been from the factory.
This custom supercharger kit is built around a Rotrex centrifugal supercharger, delivering a clean, reliable 5 PSI of boost and producing approximately 130 wheel horsepower (WHP) — up from 85 WHP stock — all while running 91-octane pump gas.
That’s a serious bump in power while keeping drivability smooth, predictable, and trail-ready.

| Setup | Wheel HP (WHP) | Crank HP |
|---|---|---|
| Stock | ~85 WHP | 114 HP |
| Supercharged (5 PSI) | ~130 WHP | 175 HP |
| Gain | +45 WHP | +61 HP |
That’s:
+45 wheel horsepower
+61 crank horsepower
~53% increase at the wheels
You’re not just adding a little pep — you’re transforming the machine:
Faster acceleration
Stronger midrange pull
Higher top-end speed
More responsive throttle
The beauty of the Rotrex centrifugal supercharger is how it delivers that power — smooth, progressive boost that feels OEM but hits substantially harder.
